MINE-GAR DUMP-REGISTERING MEAN S Application filed May 12,

With present day methods, it is diilicult to accurately keep track of the number of mine cars dumped during a day or during along-er period, but it is one object of the present invention to provide a unique register for this purpose, thereby enabling an accurate check upon the number of cars dumped during any period.

In carrying out the above end, a further object is to provide unique magnetically-actuated means for operating the register.

With the foregoing and minor objects in view, the invention resides in the novel subject matter hereinafter described and claimed, description being accomplished by reference to the accompanying drawings.

Fig. 1 is a top plan View partly broken away and in section showing the registeroperating mechanism associated with a conventional ty 3c of register.

Fig. 2 is a sectional View partly in elevation, as indicated by line 22 of Fig. 1.

Figs. 3 and i are perspective views of portions of the register-operating means.

Fig. 5 is an elevation illustrating the man ner in which the register mechanism and a clock, may be embodied in one casing.

In the drawings above briefly described, the numeral 8 denotes an appropriate casing formed of any desired material or materials. il'sxe end or this casing houses a register mechanism, portions of which are indicated at M, said mechanism being preferably such as to give a daily total and a total for a longer period, for instance, a month. The register mechanism M may be considered as of the usual axially alined roller or figure wheel type and it may be operatively connected in any appropriate manner with a shaft 9 disposed within the casing 8, said shaft being rotated in a step by step manner by the mechanism hereinafter described.

1() denotes a U-shaped member of magnetic metal, having its arms 11 turned inwardly attheir ends. ,The arn'rconnecting portion 12 of the member 10 is shown secured to the casing 8 by screws 13, and any de sired provision may be made to prevent magnetizing of the casing from said mem- 1928.

ber 10, if the casing be formed from magnetic material.

1 1 denotes a second U-shaped member whose arms straddle the end portions of the arms 11, the arm-connecting portion 16 of said member 14, being outwardly spaced from said ends of the arms 11 as shown in. Fig. 1. in. the present showing, member 15 may be considered as of iron or steel, and as it is desirable to secure its arms 15 to the arms 11, provision made to prevent magnetizing of said member 14 from said arms 11. For this purpose, L-shaped brac :ets 17' of non-magnetic material are shown, secured to the arms 11 by screws 18 and secured to lateral lugs 19 on the arms 15 of bolts 20.

Appropriate means 21 is provided between the arms 11 for magnetizing the member 10, making it possible for said arms to attract an armature 22 which is secured to a rod This rod passes slidably through openings 24 and 25 in the arm-connecting portions 12-16 of the members 10-14, and also pa ses through another opening 26 in the casing 8. A coiled compression spring 2'? surrounds a portion of the rod 23 at one of its ends abuts a collar 28 on said rod, while the other end of the spring contacts with the portion 16 of the U-shaped member 14-. At the outer side of the portion 12 of member 10, a stop 29 is provided, preferably consisting of an adjustable nut and a lock nut. Spring 27 serves to shift the rod 23 in one direction to the limit permitted by the stop 29, and when the arms 11 are magnetized by energizing of the means 21, said rod is slid longitudinally against the action of the spring 27. We utilize this motion of the rod 23, tor turning the shaft 9 a predetermined distance, a pawl 30 and ratchet wheel 31 being shown for establishing a oneway driving connection between said rod and shaft, To hold the rod 23 against rotation which would prevent proper engagement of the pawl 30 with the ratchet wheel 31:, we have illustrated a pin 32 projecting rigidly from the armature 22 and passing slidably through an opening 33 in the portion 16 of the bracket 14.

Bearings 9 are shown for the shaft 9. 100

These bearings are carried by a base plate 34 which if desired, may extend beyond said bearings to support parts of the register mechanism M. The end of the base plate 34 opposite the mechanism M, is provided with an upwardly directed flange 35 secured to the portion 16 of the member 14L, by appropriate fasteners 36, said flange being formed with an opening 37 alined with the opening 33, to accommodate the pin 32. A tubular housing 38 is rigidly carried by the flange 35 and contains the spring 27 and collar 28.

Binding posts 39 are shown for the magnetic means 21, and current conducting wires 40 lead from these binding posts to an appropriate switch (not shown).

While all parts and organizations of parts herein disclosed are intended primarily for use in a means for registering the number of mine cars dumped, it will be understood that the mechanism detailed for instance in Fig. 1, could be employed for purposes other than that described.

As excellent results are obtainable from the general construction shown and described, it is preferably followed. However, within the scope of the invention as claimed, variations may be made.

1. A mechanism of the class described comprising a U-shaped member of magnetic metal and means for magnetizing said member, a second U-shaped member having its arms secured to the arms of the first named member, the arm connecting portion of said second U-shaped member being outwardly spaced from the ends of said arms of the first named member, the arm-connecting portions of the two members having alined rodreceiving openings, a rod passing through said openings and having an armature shiftable in one direction under the influence of said magnetizing means, spring means acting against said rod and reacting against one of said arm-connecting portions for returning the rod after each magnetically effected movement thereof, and a stop on the rod at the outer side of the other of said armconnecting portions for limiting the movement of said rod under the influence of said spring means.

2. A mechanism of the class described comprising a U-shaped member of magnetic metal and means for magnetizing said member, a second U-shaped metal member whose arms straddle and are spaced from the arms of the first named member, the arm-connecting portion of said second member being outwardly spaced from the ends of the arms of the first mentioned member, brackets secured to the two sets of arms for securing them together; the arm-connecting portions of the two U- shaped members being formed with alined rod-receiving openings, a rod passing through said openings and having an armature cooperable with the arms of the first mentioned member to effect shifting of the rod in one direction when said first mentioned member is magnetized, spring means acting against said rod and reacting against one of said arm-connecting portions for returning the rod after each magnetically effected movement thereof, and a stop on the rod at the outer side of the other of said arm-connecting portions for limiting the movement of said rod under the influence of said spring means.

3. A mechanism of the class described comprising a U-shaped member of magnetic metal and means for magnetizing said member, a second U-shaped member having its arms secured to the arms of the first named member, the arm-connecting )OI'tiOIl of said second U-shaped member being outwardly spaced from the ends of said arms of the first named member, the arm-connecting portions of the two members having alined rod-receiving openin s, a rod passing through said openings and having an armature shiftable in one direction under the influence of said agnetic means, spring means acting against said rod and reacting against one of said arm-connecting portions for returning the rod after each magnetically efl'ected movement thereof, a stop on said rod at the outer side of the other of said arm-connecting portions for limiting the movement of said rod under the influence of said spring means, a beairing-supporting base having a flange secured to the outer side of said one of said armconnecting portions, and a housing for the aforesaid spring means carried by said flange.

In testimony whereof we have hereunto afiixed our signatures.
